Computer Vision Syndrome (CVS) is a condition that affects millions of people worldwide. It is a combination of physical symptoms caused by extended computer use. Common symptoms include eyestrain, dry eyes, headaches, blurred vision, neck and shoulder pain, and light sensitivity. Eyestrain is the most common symptom of CVS, which is caused by focusing on a computer screen for long periods of time without a break. The eyes will become tired, leading to blurred vision, headaches, and difficulty focusing. To prevent eyestrain, take frequent breaks and avoid looking at bright screens for too long. Adjust your computer monitors position and brightness to the most comfortable level. Dry eyes can also be caused by extended computer use. If your eyes become too dry, they may become red and itchy. To combat dry eyes, use lubricating eye drops on a regular basis and blink often when viewing a computer screen. Headaches are another common symptom of CVS. They often occur when a person is staring at a computer screen too long without taking a break. Taking regular breaks, sleeping adequately, and reducing stress levels can help to reduce the occurrence of headaches. CVS can also lead to neck and shoulder pain. Many people sit in the same position when viewing a computer screen. To prevent this, make sure to switch positions frequently, sit up straight, and use an ergonomic chair with adjustable arm rests. Finally, light sensitivity can also be a sign of CVS. To prevent this, adjust the brightness and contrast of your monitor to the most comfortable level. Also try to minimize exposure to bright light and reduce the amount of time spent in windowed rooms such as an office or living room. Computer Vision Syndrome can be uncomfortable and irritating, but it is usually easy to manage with a few simple steps. Taking frequent breaks, adjusting the brightness and contrast of the monitor, lubricating your eyes regularly, sleeping enough, and reducing stress levels will go a long way towards improving your eye health and reducing the effects of CVS.
